An Example of Technical plan
Provided field data: the initial mud layer depth is 15 meters,the dredging depth is about 10-15 meters,and the average width of the lake is 10 meters.
So,considering small capacity ships,the total width is limited to about 5 meters (to be verified). The ship has no self-propelled capability and is towed by cables or yacht-like equipment.
Recommended ship structure
The above structure is a reference structure. The cutter suction equipment is lowered vertically to the bottom of the river to pump mud and sand,and the mud discharge port is discharged from the stern end of the ship and connected to the mud discharge pipe.
